This is pointless. I am using your newest version. I am not stupid you know I am WELL aware of how to release a CPU and how to research and how to play this simple game. Unfortunately it does not work and so I am moving on, you lost a player.
Viewing post in Research / Development @ In Game
I assumed you were describing your steps in detail and saw no trace of actually releasing a CPU, hence my mistake.
Unfortunately, I am not able to reproduce the said issue in either Chrome, Edge or Explorer. I know of people playing in Opera, Safari and Firefox who did not have such problems with the game. Please let me know what browser you are using, so I can investigate further.
In the meantime, you can try clearing the browser cache, or simply downloading the windows release from the page you linked.
